What causes vaginitis?
Infectious causes of vaginitis include bacteria, yeast, and Trichomonas.
- Bacterial vaginosis is the most common bacterial infection that causes vaginitis. This condition results from an imbalance of overgrowth in the bacteria normally present in the vagina. It is not clear if sexual activity plays a role in the development of bacterial vaginosis, and some experts believe it can occur in women who have not had sexual contact. The STDs gonorrhea and Chlamydia are other bacterial causes of vaginitis.
- Yeast infections, such as Candida infection, are a common cause of vaginitis. Yeast infections are not considered to be STDs.
- Trichomonas ("Trich") is a parasitic infection that is transmitted through sexual contact.
- Non-infectious causes of vaginitis include physical or chemical irritation,
- Douches, soaps, or fragrances
- Reduced estrogen levels around the time of menopause
Vaginitis in young girls has also been described and is thought to arise from poor hygiene practices that allow the spread of fecal bacteria from the anal area into the vagina.
